There could be a heavy cost involved, hauling off soil to a certified toxic-waste-receiving-dump. (This is not all bad, because it will give excavation contractors some work)<br /><br />About fifteen years ago, the airlines switched over from Ethylene Glycol to the much less toxic Propylene Glycol. This foresight may have helped the contamination problem, but we will probably need to drill some test holes in the affected earth, before we can build anything new. <br /><br />The spots where Sky West and Horizon currently deice their aircraft (actually, hardly ever in August) will be easy to pinpoint, because they have always performed their deicing procedures in that concentrated area. However, the private vendor and its previous incarnations have for year’s deiced aircraft in various spots, to the sides of the taxiway. <br /><br />This too, may have given us some advantage –the spreading out of the toxins. And as water has amazing dissolution powers, the plenteous rain we’ve received in recent years, probably has helped this problem. However, this whole deicing contamination issue is something we will need to examine closer within a few years.JBanholzerhttps://www.blogger.com/profile/12410822155850772756noreply@blogger.com
